Quite right. > As long as an altruistic gene is able to detect another copy of itself in another organism, AND it's not even "detection"... it JUST HAPPENS if the behavior in a population _results_ in a population where more copies of the gene survive, it requires no "detection" at all. That's the thing about natural selection, it just happens as a byproduct of genes changing and having differential survival, there is no need for the organisms involved to have any method whatsoever of detecting anything.
